MARKING ATTACHMENT FOR TYPEWRITING-MACHINES.

Specification of Letters Patent.

llatented Feb. 15, 1921.

Application filed September 13, 1919. Serial No. 323,547.

To all whom it may concern.

Be it known that I, ALFRED A. E. HANsEN, a citizen ofthe United'States,residing at Philadelphia, in the county of Philadelphia and State ofPennsylvania, have invented certain new and useful Improvements inMarking Attachments for Ty ewriting-Macliines, of which the followmg isa specification. A

This invention relates to a marking or ruling attachment for typewritingmachines, and an object of the invention is to provide an attachment fortypewriting machines by means of which any part of the subject matterbeing written by the ty ewriting machine may be quickly and easi yunderscored with a continuous line eliminating the necessity of therepeated operation of the underscoring character key of the typewritingmachine, and also an attachment by means of which the paper which isplaced over the platen of the typewriting machine may be ruled bothlaterally and longitudinally as desired.

Another object of this invention is to provide a marking attachment fortypewriting machines embodying a graduated scale, which adjustablycarries a stylus or marker carrying arm for longitudinal movementthereover to permit the positioning of the marker at any desiredpredetermined position along the length of the platen" of thetypewriting machine and also to provide a structure of this nature whichmay be built into typewritlng machines or easily and convenientlyattached to typewriting machines of approved types by any person havingany knowledge whatsoever of a typewriting machine.

ore specifically, the invention comprehends the provision of a markingattachment for typewriting machines including a graduated scale havingmeans associated therewith for attaching it to a typewriting machine,which scale is provided with an upper and a lower set of recesses alongits opposite sides serving as means to facilitate the attachment of themarking device, such as a jencil, pen, ruling pen, or stylus to thescale, and also to facilitate the attachment of paper guides to thescale, which paper guides are preferably constructed of spring steel andhave portions for frictionally engaging the graduated scale, to permitmovement of the paper guides over the scale,

and also to permit the paper detached from the attachment if desired.

Other objects of the invention will appear in thefollowing detaileddescription taken n connection with the accompanying drawlugs, forming apart of this specification, andan' which drawings:

Fig. 6 is a front elevation of a modified form of the marking attachmentof the typewriting machine, and

Fig. 7 is a cross section taken on the line 7-7 of Fig. 6.

Referring more particularly to the drawings, the marking attachmentfortypewriting machines includes a graduated Scale 10,

I be built into the typewriting guides to be which may machine ii.desired, or which may be attached to the frame A of any suitable type oftypewriting machines in any suitable manner, such as by clamp structure11, the specific construction of which might be varied to fit variousapproved makes of typewriting machines. This graduated scale vided witha pair oi longitudinally extending ways or recesses 12, in oppositesides near its upper edges, which ways or recesses receive thereinbearing balls 13, carried by the lower forked end of the supportingstandard 15, for permitting free, and unimpeded sliding movement of thestandard 15 longitudinally over the scale or graduated guide 10. Thisstandard 1?) curves toward one end of the scale 10, as clearly shown infor the pin 20 carried centrally by the head 21, which is formed uponthe arm 17.' The ring 19 is provided with a cut out port1on 22, therein,which is adapted to receive a lug 23 carried by the pin 20, through asideopening 22' in the ring 19, for locking the standard '15 and arm 17in predetermined adjusted ositions. A fiat spring 24 is mounted withinthe hollow space between the facing sides of the heads 18 and 21 at oneend of which spring 24 engages lug 25 1 carried by the head 18, whilethe opposite end of the spring engages against a pin 26 carried by thehead 21, the said pin tending to urge the arm 17 into such position wlthrespect to the standard 15 that the lugs 23 will be engaged in the cutout portion 22.

The arm 17 has an angularly disposed socket 27 carried by its outer end,which socket has a marker receiving opening extoward the arm 17 asclearly shown in Fig;

5 of the drawings, to adapt it for receiving various sized markers, andthese inclined sides together with the thumb screw 28 will hold anymarker which may be received through the opening in firm engagement withthe socket and also with the arm 17.

The graduated scale or bar 10 is provided with a second opposed'pair oflongitudi-j nally extending recesses 30, which are provided to receivethe curved end 31 of the attaching clip 32, ofthe paper guides 33. Thesepa er guides are preferably constructed 0 spring steel and one of theattaching clips 32 is formed integrally therewith while the other isattached thereto, as clearly shown in Fig. 2 of the drawings. Theresiliency ,of these attaching clips 32 will cause limited frictionalengagement between the attaching strips and the scale 10 sufficient tohold the paper guides 33 in adjusted positions longitudinally along-thescale 10 and will also permit the ready attachment of the paper guidesor the ready attachment to or detachment from the scale as desired. Thepaper guides 33 are arcuate, they being scribed upon the samecommoncentefwith the platen B of the typewriter machine, and havingtheir inner faces spaced slightly from the outer surface of the platen Bby means of the usual type of roller 34; the said guides curving toguide their paper over the platen and hold it in engagement with theplaten, as is necessary in the proper operation of typewriting machines,and which is also necessary to insure the proper operation of themarking attachment, in that the pgaper must be held firmly against theplaten to insure regular lines upon the paper by the marker 16.

The standard 15 and arm 17, are shaped so that the pencil or othermarker 16 will be positioned to properly engage paper graduations 35 ofthe scale, and as the paper is wrapped over the platen B, the marker 16will rule'itv 7 Figs. 6 and 7 illustrate a modified form of theinvention showing the marking attach ment adapted for attachment to atypewriting machine of the Underwood, Royal, and 1 Monarchtypes, inwhichmodified form the paper guides 40 are carried by the lower scale41, which form a part of the attachment. In this type of typewritinmachines the usual paper gui es exten platen from the rear, when it willbe necessary to remove them prior to attaching the improved markingattachment to the machine. is attached to the typewriter frame D byclamp structures 42, analogous to the clamps 11 and the second orforward lower scale 41 is connected to the upper scale 10' by suitableconnecting bars 43 in such manner The improved marking attachment overthe v that the scale '41 will be pos'tioned overthe platen C, forwardlyof an below the scale 10, which latter scale carries a marker supportingstandard 15, arm 17, and a marker 16'. This marker supporting structureis similar in construction to the preferred form illustrated in Figs. 1to 5 of the draw- 1n 10 is free from the lower setof longitudinallyextending grooves as shown in the preferred form, it being merelyprovided However, the scale or graduated barwith theupper opposed pairof longitudinally extending recesses 12 which. receive therein bearingballs 13, carried by the lower forked end of the standard 15 tofacilitate the longitudinal movement of the marker structure over theplaten.

The paper guides 40 are provided with suitable resilient clampingportions 43 which engage over the scale 41, frictionally engaging thescale, sufliciently to maintain the paper guides in various adjustedpositions upon the scale and in such manneras' Y vention, and thatchanges in etails, such as would be necessary to render the deviceapplicable for attachment to various types of typewriting machines canbe made, along the methods first treated for each particular type oftypewriting machines, without departing from the spirit ofthis'invention, and provided suchehanges or alterations are comprehendedwithin is claimed.
